A cat pricks it's ears to increase fidelity of it's hearing, dogs point with their nose as a learned trait they don't do it in the wild. None of these behaviours are naturally evolved communication methods This is pure speculation. Who is to say that learned traits can or cannot evolve naturally, over time? Besides, your use of "it's" is wrong. An underlying assumption of the statement "pointing declaratively" is that there's some one or some thing to be declarative to (as in an audience, or partner, or fellow pack member). I liked the article, but it did go about assuming that humans are the only creatures who know how to be declarative. We're probably more verbally declarative than any other species, but I highly doubt we're the only "declarative" species out there.
